The hallmarks of aging

Aging is a natural and inevitable process that affects all living organisms. In humans, aging is associated with a variety of changes at the cellular, tissue, and organ level that can result in a decline in function and an increased susceptibility to disease and death. Some of the hallmarks of aging in a medical context include:

  1. Genomic instability: This refers to damage or changes in the DNA that occur as a result of aging, which can lead to mutations and genetic abnormalities that contribute to age-related diseases.

  2. Telomere attrition: Telomeres are the protective caps on the ends of chromosomes that shorten with each cell division. As telomeres become shorter, cells become more vulnerable to damage and senescence, leading to aging.

  3. Epigenetic alterations: Epigenetic changes refer to modifications to the DNA that affect gene expression. These changes can accumulate over time and contribute to age-related diseases.

  4. Loss of proteostasis: Proteostasis refers to the balance of protein production, folding, and degradation in cells. As we age, this balance can be disrupted, leading to the accumulation of damaged and misfolded proteins that can cause cellular damage and contribute to age-related diseases.

  5. Deregulated nutrient sensing: Nutrient sensing pathways play a crucial role in regulating metabolism and energy homeostasis. As we age, these pathways can become dysregulated, leading to metabolic dysfunction and an increased risk of age-related diseases.

  6. Mitochondrial dysfunction: Mitochondria are the cellular organelles responsible for producing energy. As we age, mitochondrial function can decline, leading to decreased energy production and an increased susceptibility to cellular damage.

  7. Cellular senescence: Cellular senescence refers to the process by which cells stop dividing and become irreversibly arrested in a state of growth arrest. Senescent cells can accumulate over time and contribute to tissue dysfunction and age-related diseases.

In addition to the seven hallmarks of aging previously mentioned, Lopez et al. (2013) identified two more hallmarks of aging:

  • loss of cellular communication and
  • stem cell depletion.

The loss of cellular communication refers to the disruption of communication between cells, tissues, and organs that occurs with aging, which can lead to tissue dysfunction and an increased risk of disease.

Stem cell depletion refers to the decline in the number and function of stem cells that occurs with aging, which can contribute to age-related tissue dysfunction and an increased risk of disease.

These two additional hallmarks of aging identified by Lopez et al. are important factors in the aging process and have significant implications for human health, as they can contribute to the development of a wide range of age-related diseases and disorders.

Understanding these hallmarks of aging is essential for developing strategies to promote healthy aging and prevent age-related diseases.

GHK-Cu

GHK-Cu is a peptide that is naturally produced in the human body through the process of tissue repair and regeneration. The formation of GHK-Cu occurs when the tripeptide Glycine-Histidine-Lysine (GHK) binds to a copper ion (Cu), forming the GHK-Cu complex.

GHK-Cu can be found in various tissues and fluids throughout the body, including blood plasma, saliva, and urine. It plays a role in several biological processes, including wound healing, tissue remodeling, and immune response modulation.

GHK-Cu (glycyl-L-histidyl-L-lysine copper) is a small protein that has been shown to play an important role in the stem cell process:

– GHK-Cu promotes stem cell mobilization and homing – It acts as a signaling molecule that recruits stem cells from the bone marrow and helps them migrate to areas of injury or inflammation. This is useful for directing stem cells to tissues needing repair.

– It stimulates proliferation of stem cells – GHK-Cu increases the replication rate of various stem cells like mesenchymal, epithelial and hematopoietic stem cells. This expands the number of stem cells available for therapeutic use.

– It protects stem cells from oxidative stress – As an antioxidant, GHK-Cu helps reduce damage from reactive oxygen species and increase stem cell survival. This maintains stem cell integrity.

– It supports angiogenesis from stem cells – Angiogenesis or new blood vessel formation is important for wound healing. GHK-Cu helps stimulate blood vessel growth using stem cell derived factors.

– It facilitates differentiation of stem cells – Treatment with GHK-Cu has been shown to direct stem cells towards forming specific tissues like skin, bone, cartilage based on environment cues.

– Anti-inflammatory effects – The anti-inflammatory properties of GHK-Cu help create a favorable environment for transplanted stem cells and reduce rejection.

– Enhancement of stem cell therapy: GHK-Cu has been shown to enhance the effectiveness of stem cell therapy by improving the survival, migration, and differentiation of transplanted stem cells.

Overall, GHK-Cu appears to play an important role in regulating the activity of stem cells, which are critical for tissue repair and regeneration. By promoting the mobilization, activation, and protection of stem cells, GHK-Cu may help to enhance the body’s natural ability to heal itself, as well as improve the effectiveness of stem cell-based therapies.

Here are some relevant research references on the role of GHK-Cu in stem cell therapies:

Stem cell activity is an important area of research in anti-aging and regenerative medicine, as it plays a crucial role in tissue repair and regeneration. Stem cells have the ability to self-renew and differentiate into multiple cell types, making them a promising tool for regenerating damaged tissues and organs.

As we age, the number and activity of stem cells in our bodies decline, which can lead to a decreased ability to repair and regenerate tissues. This decline in stem cell activity has been implicated in the aging process and in the development of age-related diseases.

In recent years, there has been growing interest in using stem cells for anti-aging therapies. Researchers are investigating ways to boost stem cell activity and function, either by stimulating the body’s own stem cells or by using stem cells from external sources.

One promising approach is to use small molecules, such as peptides or growth factors, to stimulate stem cell activity. For example, GHK-Cu is a naturally occurring peptide that has been shown to promote stem cell proliferation and migration, as well as tissue repair and regeneration.

In addition to stimulating stem cell activity, researchers are also exploring ways to use stem cells for tissue engineering and regenerative medicine. For example, stem cells can be used to create replacement tissues or organs for patients with age-related diseases or injuries.

Overall, stem cell activity is an important area of research in anti-aging and regenerative medicine, and has the potential to provide new therapies for age-related diseases and conditions.

The building blocks for GHK-Cu come from the dietary intake of proteins that contain the amino acids glycine, histidine, and lysine. These amino acids are essential for the synthesis of GHK, which can then bind with copper to form GHK-Cu. Copper is obtained from various food sources, including shellfish, nuts, seeds, and dark leafy greens. Once the GHK-Cu complex is formed, it can be utilized by the body for its various functions.

NRF2 and GHK-Cu are both involved in regulating cellular processes and have been studied for their potential anti-aging and health-promoting effects.

NRF2 is a transcription factor that plays a critical role in cellular defense mechanisms against oxidative stress and inflammation. It regulates the expression of genes involved in antioxidant defense, detoxification, and other cytoprotective pathways. Activation of NRF2 has been linked to a variety of health benefits, including protection against cardiovascular disease, neurodegenerative disorders, and cancer.

GHK-Cu, on the other hand, is a naturally occurring peptide that has been shown to have anti-aging effects. It has been found to promote collagen synthesis, increase antioxidant activity, and enhance wound healing. GHK-Cu also stimulates the production of growth factors, such as insulin-like growth factor-1 (IGF-1), which plays an important role in tissue repair and regeneration.

There is some evidence to suggest that NRF2 and GHK-Cu may interact to promote cellular health and longevity. One study found that treatment with GHK-Cu increased NRF2 activity in human skin cells, leading to increased antioxidant activity and protection against oxidative stress. Other studies have suggested that NRF2 activation may be involved in the anti-aging effects of GHK-Cu.

Overall, while the relationship between NRF2 and GHK-Cu is not yet fully understood, there is evidence to suggest that they may work together to promote cellular health and longevity.


NRF1 and GHK-Cu are also involved in regulating cellular processes and have been studied for their potential anti-aging and health-promoting effects.

NRF1 is a transcription factor that plays a critical role in regulating the expression of genes involved in mitochondrial biogenesis, function, and energy metabolism. It has also been implicated in the regulation of cellular antioxidant defenses, protein quality control, and the unfolded protein response. Activation of NRF1 has been linked to improved mitochondrial function, increased energy production, and protection against oxidative stress.

GHK-Cu, as mentioned before, is a naturally occurring peptide that has been shown to have anti-aging effects. It has been found to promote collagen synthesis, increase antioxidant activity, and enhance wound healing. GHK-Cu also stimulates the production of growth factors, such as insulin-like growth factor-1 (IGF-1), which plays an important role in tissue repair and regeneration.

There is limited research on the relationship between NRF1 and GHK-Cu, but some studies have suggested that GHK-Cu may stimulate NRF1 activity. For example, one study found that treatment with GHK-Cu increased NRF1 expression in human skin fibroblasts, leading to increased mitochondrial biogenesis and improved cellular energy metabolism. Another study reported that GHK-Cu enhanced NRF1-mediated gene expression in liver cells.

Overall, while the relationship between NRF1 and GHK-Cu is not yet fully understood, there is some evidence to suggest that GHK-Cu may stimulate NRF1 activity, leading to improved mitochondrial function and energy metabolism. Further research is needed to fully elucidate the relationship between these two factors.


NAD (nicotinamide adenine dinucleotide) and GHK-Cu are two molecules that have been studied for their potential anti-aging effects and their roles in regulating cellular processes.

NAD is a coenzyme that plays a critical role in energy metabolism and cellular processes such as DNA repair, gene expression, and cell signaling. NAD levels decline with age, and this decline has been implicated in age-related diseases and conditions.

GHK-Cu, on the other hand, is a naturally occurring peptide that has been shown to have anti-aging effects. It has been found to promote collagen synthesis, increase antioxidant activity, and enhance wound healing. GHK-Cu also stimulates the production of growth factors, such as insulin-like growth factor-1 (IGF-1), which plays an important role in tissue repair and regeneration.

There is some evidence to suggest that GHK-Cu may increase NAD levels and activate pathways that are involved in NAD metabolism. For example, one study found that treatment with GHK-Cu increased NAD levels in human fibroblast cells. Another study reported that GHK-Cu increased the activity of an enzyme called NAMPT, which is involved in NAD synthesis.

Additionally, NAD is required for the activity of an enzyme called sirtuin 1 (SIRT1), which is involved in regulating cellular processes such as DNA repair and gene expression. GHK-Cu has been shown to activate SIRT1, and this activation may be mediated in part by increases in NAD levels.

Overall, while the relationship between NAD and GHK-Cu is not yet fully understood, there is some evidence to suggest that GHK-Cu may increase NAD levels and activate pathways involved in NAD metabolism, which may contribute to its anti-aging effects.

Glutathione

Glutathione is a powerful antioxidant that plays a crucial role in the body’s defense against oxidative stress, which can damage cells and contribute to the development of various diseases. Glutathione is made up of three amino acids: cysteine, glutamic acid, and glycine. It is produced naturally by the body and found in every cell.

One of the primary functions of glutathione is to neutralize free radicals and other reactive oxygen species (ROS) that can damage cells and DNA. It also helps to regenerate other antioxidants like vitamins C and E, which further enhances the body’s ability to fight oxidative stress.

Glutathione also plays a critical role in the immune system, particularly in the function of T-cells. It helps to maintain the integrity and activity of these cells, which are essential for fighting infections and cancer.

In addition, glutathione is involved in many other cellular processes, including protein synthesis, DNA synthesis and repair, and the breakdown of toxins and carcinogens in the liver. Overall, glutathione is essential for maintaining the health and function of the body’s cells and tissues.

The 10 functions of glutathione in the human body are:

  1. Antioxidant activity: Glutathione helps protect cells from damage caused by free radicals and oxidative stress, which can lead to inflammation, DNA damage, and chronic disease.

  2. Detoxification: Glutathione plays a key role in the detoxification of harmful substances in the body, by binding to and eliminating toxins through urine or bile.

  3. Immune support: Glutathione is important for immune system function, as it helps to activate and enhance the activity of immune cells, such as T cells and natural killer cells.

  4. Protein synthesis: Glutathione is involved in the synthesis and repair of proteins in the body, which is important for maintaining cellular function and preventing damage.

  5. Energy production: Glutathione helps to maintain optimal mitochondrial function, which is important for the production of energy in the body, and preventing cellular damage caused by oxidative stress.

  6. Regulation of cell death: Glutathione can regulate programmed cell death (apoptosis), which is important for maintaining proper tissue function and preventing the growth of abnormal cells, such as cancer cells.

  7. Anti-inflammatory activity: Glutathione has anti-inflammatory effects that can help reduce inflammation in the body, and protect against chronic diseases, such as arthritis and heart disease.

  8. Skin health: Glutathione can help protect the skin from damage caused by UV radiation and other environmental stressors, and may have anti-aging effects by reducing oxidative stress and inflammation.

  9. Neuroprotection: Glutathione is important for brain function and has been shown to protect against neurodegenerative diseases, such as Alzheimer’s and Parkinson’s disease.

  10. Cardiovascular health: Glutathione can help protect the cardiovascular system by reducing oxidative stress and inflammation, improving blood vessel function, and reducing the risk of heart disease.

Glutathione is an important antioxidant that plays a key role in protecting cells from oxidative stress and free radical damage. While supplementing with glutathione may seem like a simple way to boost antioxidant levels, there are several challenges associated with this approach:

  1. Poor absorption: Oral glutathione supplements may not be well-absorbed by the body, as glutathione is rapidly broken down in the digestive system. This means that the amount of glutathione that actually reaches the cells and tissues may be limited.

  2. Expense: Glutathione supplements can be expensive, particularly when compared to other antioxidants such as vitamin C or vitamin E.

  3. Short half-life: Glutathione has a short half-life in the body, meaning that it is quickly broken down and excreted. This means that frequent dosing may be necessary to maintain optimal glutathione levels.

  4. Interactions with medications: Glutathione may interact with certain medications, such as chemotherapy drugs, and may affect their efficacy. It is important to talk to a healthcare provider before taking glutathione supplements if you are taking any medications.

  5. Potential side effects: While glutathione is generally considered safe, some individuals may experience side effects such as bloating, gas, or diarrhea.

Given these challenges, some researchers have suggested that other approaches, such as increasing the body’s own production of glutathione, may be more effective in boosting glutathione levels. It is important to consult with a healthcare provider before taking any supplements, including glutathione, to determine the best approach for your individual needs.

There are several ways to boost your own glutathione production naturally:

  1. Eating a healthy diet: Consuming a diet that is rich in nutrients such as vitamin C, vitamin E, selenium, and sulfur-containing amino acids like cysteine, can help support the body’s own production of glutathione.

  2. Exercise: Regular exercise has been shown to increase glutathione production in the body, as well as reduce oxidative stress.

  3. Get enough sleep: Getting adequate sleep is important for many aspects of health, including glutathione production. Studies have shown that sleep deprivation can reduce glutathione levels in the body.

  4. Reduce stress: Chronic stress can lead to increased oxidative stress and a decrease in glutathione levels. Engaging in stress-reducing activities such as yoga, meditation, or deep breathing can help support glutathione production.

It’s important to note that while these strategies may help support the body’s own production of glutathione, they may not be sufficient in cases where glutathione levels are severely depleted. In these cases, supplementation may be necessary under the guidance of a healthcare provider.

Carnosine

Carnosine is a dipeptide made up of the amino acids beta-alanine and histidine. It is found in high concentrations in muscle tissue, particularly fast-twitch muscle fibers.

Carnosine is known to have several important roles in the body. One of its primary functions is as a buffer against acidic conditions in muscle tissue during high-intensity exercise. By buffering the acidity, carnosine helps to delay the onset of fatigue and allows for longer periods of high-intensity exercise.

Carnosine is also a powerful antioxidant and is particularly effective at scavenging harmful reactive oxygen species (ROS) that can damage cells and contribute to the development of various diseases. It is able to protect against oxidative stress in various tissues throughout the body, including the brain and eyes.

In addition, carnosine has been shown to have several other potential health benefits, such as reducing inflammation, improving insulin sensitivity, and promoting healthy aging. It may also have a role in protecting against certain age-related diseases, such as Alzheimer’s disease and cataracts.

Overall, carnosine is an important compound in the body that has several functions, including buffering against acidity in muscle tissue, acting as an antioxidant, and potentially providing other health benefits.

Carnosine is a dipeptide made up of the amino acids beta-alanine and histidine. Here are 10 important functions of carnosine in the human body:

Eating a balanced diet that includes a variety of these foods can help indirectly increase beta-alanine levels in the body. However, taking beta-alanine supplements is a more reliable way to increase beta-alanine levels.

The making of GHK-Cu also requires enough Cu2+ ions. 

The recommended daily intake of copper for adults is between 900 and 1,000 micrograms (mcg). The exact amount you need may depend on your age, gender, and specific health needs.

The Recommended Dietary Allowance (RDA) for copper is:

  • 900 mcg for adult men
  • 700 mcg for adult women
  • 890-1,000 mcg for pregnant women
  • 1,300-1,400 mcg for lactating women

Copper is an essential nutrient that is important for the proper functioning of the body.

It is involved in the metabolism of iron, the production of collagen, and the maintenance of nerve function, among other things.

Most people can get all the copper they need by consuming a varied diet that includes a variety of plant and animal-based foods. However, if you are concerned about your copper intake, it’s a good idea to talk to a healthcare provider or registered dietitian. They can help you determine if you are getting enough copper in your diet and make recommendations for how to ensure that you are meeting your nutritional needs. DO NOT SUPPLEMENT COPPER (or iron) WITHOUT MEDICAL INDICATION.

Copper is an essential trace mineral that is important for the proper functioning of the body. It is found in a wide variety of foods, with the highest concentrations typically found in organ meats, shellfish, nuts, and seeds.

Some specific foods that are high in copper include:

  • Liver (beef, chicken, pork, etc.): This is one of the best sources of copper, with a 3-ounce serving of beef liver providing over 13 milligrams (mg) of copper.

  • Oysters: These shellfish are high in copper, with a 3-ounce serving providing almost 6 mg of the mineral.

  • Nuts and seeds: Many nuts and seeds are good sources of copper, including almonds, cashews, peanuts, and sunflower seeds.

  • Legumes: Beans and lentils are good sources of copper, with a 1-cup serving of cooked beans or lentils providing around 1-2 mg of the mineral.

  • Dark chocolate: This is a good source of copper, with a 1-ounce serving providing approximately 0.9 mg of the mineral.

It’s important to note that the amount of copper in food can vary depending on factors such as the soil in which the food was grown and the methods used to process and prepare the food. It’s also important to get copper from a varied diet, as relying on a single food source for this essential mineral may not provide all the nutrients you need.

Photobiomodulation

Photobiomodulation (PBM) is the use of low-level light therapy to stimulate or suppress cellular functions in living tissue. This technique involves the application of light to tissues. The light can be absorbed by chromophores within the cells, leading to changes in cell activity and metabolism.

PBM has been used for a variety of purposes, including pain relief, wound healing, reducing inflammation, and improving skin conditions.

It has been studied extensively for its potential in promoting tissue repair and regeneration, as well as for its potential to improve cognitive function and mental health.

PBM is generally considered safe when used correctly, but it should be used under the guidance of a qualified healthcare professional.

The production of vitamin D is not considered a form of photobiomodulation because it is a natural physiological process that occurs in response to UVB radiation from sunlight. However, both vitamin D production and photobiomodulation involve the absorption of light energy by cells and can have beneficial effects on human health.

When UVB radiation penetrates the skin, it stimulates the production of vitamin D3 in the body, which is then converted to its active form in the liver and kidneys. Vitamin D plays a crucial role in bone health and has been linked to a variety of other health benefits, including immune system function, cancer prevention, and mood regulation.

Photobiomodulation, on the other hand, involves the application of specific wavelengths of light to the skin or other tissues in order to modulate cellular activity and promote healing and regeneration. This technique can be used to treat a variety of conditions, such as pain, inflammation, and skin disorders.

While vitamin D production and photobiomodulation are not the same thing, they are both examples of the ways in which light energy can impact human health and well-being.

Light energy can impact human health and well-being in a variety of ways. Here are some examples:

  1. Vitamin D production: As I mentioned earlier, sunlight contains ultraviolet B (UVB) radiation, which triggers the production of vitamin D in the skin. Vitamin D is essential for bone health and immune function.

  2. Regulation of circadian rhythms: Exposure to light, particularly in the blue wavelength range, can affect the body’s circadian rhythms, which regulate sleep, mood, and other physiological processes. Exposure to blue light in the morning can help to reset the body’s internal clock and promote alertness, while exposure to blue light at night can disrupt sleep and interfere with the body’s natural rhythms.

  3. Photobiomodulation: As I mentioned earlier, photobiomodulation involves the use of light therapy to modulate cellular activity and promote healing and regeneration. This technique has been used to treat a variety of conditions, including pain, inflammation, and skin disorders.

  4. Mood regulation: Exposure to natural light has been linked to improved mood and reduced symptoms of depression. This may be due in part to the fact that sunlight triggers the release of serotonin, a neurotransmitter that helps to regulate mood.

  5. Skin health: Exposure to light, particularly in the UV range, can have both positive and negative effects on the skin. While excessive exposure to UV radiation can lead to skin damage and an increased risk of skin cancer, moderate exposure to UV radiation can help to treat certain skin conditions, such as psoriasis and eczema.

These are just a few examples of how light energy can impact human health and well-being. The specific effects will depend on the type of light exposure and the individual’s unique biology and circumstances.

Here are 20 more examples of how light energy can impact human health and well-being:

  1. Seasonal affective disorder (SAD): Exposure to bright light, particularly in the blue wavelength range, can help to alleviate symptoms of SAD, a type of depression that typically occurs in the winter months.

  2. Cognitive function: Exposure to blue light has been shown to improve cognitive function and attention, particularly in older adults.

  3. Eye health: Exposure to UV radiation can increase the risk of cataracts and other eye diseases, while blue light exposure has been linked to age-related macular degeneration.

  4. Headaches: Certain types of light, particularly flickering or flashing light, can trigger headaches and migraines in some individuals.

  5. Hormone regulation: Exposure to light can affect the body’s production of hormones, including melatonin, which helps to regulate sleep.

  6. Immune system function: Exposure to certain wavelengths of light, particularly in the blue and red ranges, can boost immune system function and help to fight infections.

  7. Athletic performance: Exposure to red light has been shown to improve athletic performance and reduce muscle fatigue.

  8. Dental health: Exposure to blue light can activate certain dental materials, improving their effectiveness in treating tooth decay.

  9. Wound healing: Exposure to certain wavelengths of light, particularly in the red and near-infrared ranges, can promote wound healing and tissue regeneration.

  10. Cancer treatment: Photodynamic therapy, a type of light therapy that involves the use of photosensitizing agents and specific wavelengths of light, is used to treat certain types of cancer.

  11. Dental aesthetics: Certain types of light, such as blue or violet light, are used in teeth whitening treatments to activate hydrogen peroxide, which helps to remove stains from teeth.

  12. Blood pressure regulation: Exposure to bright light, particularly in the morning, has been shown to lower blood pressure in people with hypertension.

  13. Migraine treatment: Transcranial photobiomodulation, a type of light therapy that involves applying light to the head, has been shown to be effective in reducing the frequency and severity of migraines.

  14. Cancer prevention: Exposure to natural light has been associated with a reduced risk of some types of cancer, including breast and colon cancer.

  15. Allergies: Light therapy has been used to treat allergies by suppressing the immune system’s response to allergens.

  16. Post-traumatic stress disorder (PTSD): Exposure to red light has been shown to reduce symptoms of PTSD, including anxiety and insomnia.

  17. Jet lag: Exposure to bright light, particularly in the morning, can help to reset the body’s internal clock and reduce symptoms of jet lag.

  18. Diabetes: Exposure to red light has been shown to improve glucose metabolism and insulin sensitivity in people with diabetes.

  19. Hair growth: Low-level light therapy has been used to stimulate hair growth in people with androgenetic alopecia.

  20. Aging: Exposure to light, particularly in the blue and near-infrared ranges, has been shown to have anti-aging effects on the skin and promote the production of collagen and elastin.

X39 light energy patches are a type of wearable phototherapy device designed to deliver low-level light energy to the body. These patches contain a proprietary blend of amino acids and crystals that are activated by body heat and light, and they are designed to promote healing and reduce inflammation throughout the body.

The technology behind X39 patches is based on photobiomodulation, a process by which certain wavelengths of light energy are absorbed by cells in the body, triggering a cascade of beneficial physiological responses. According to the manufacturer, X39 patches deliver a specific wavelength of near-infrared light energy that is designed to stimulate the production of a peptide called copper peptide GHK-Cu, which plays a role in a variety of cellular functions, including wound healing, tissue repair, and immune regulation.

X39 patches are applied directly to the skin, typically on the back of the neck or the upper arm, and are designed to be worn for up to 12 hours at a time. They are marketed as a non-invasive, drug-free alternative to traditional medical treatments, and are claimed to be effective for a variety of conditions, including pain, inflammation, and reduced energy levels. However, more research is needed to fully evaluate the efficacy and safety of X39 patches for these uses. 

In the United States, medical devices are regulated by the Food and Drug Administration (FDA), which is responsible for ensuring the safety and effectiveness of these products. The FDA classifies medical devices into different categories based on the level of risk they pose to patients, and each category has its own regulatory requirements.

The LifeWave X39 patches are classified by the FDA as a Class I medical device, which includes low-risk devices. Class I devices are generally exempt from the premarket review process and are subject to general controls, such as labeling requirements and adherence to good manufacturing practices.

LifeWave has stated that its X39 patches comply with all FDA regulations and that the company has obtained a Medical Device Establishment Registration and Device Listing with the FDA.

In addition to the United States, LifeWave markets its products in over 80 countries worldwide, and the company complies with the regulatory requirements of each of these countries as well.

LifeWave patches are sold through affiliated doctor practices, and authorized, independent re-sellers/distributors. The company is privately owned and headquartered in San Diego CA. All R&D, and manufacturing are sourced from and done within the US.

FREQUENTLY ASKED QUESTIONS relating to GHK-Cu and/or stem cell activation in general

DISCLAIMER: the information below is about stem cells in general and not meant as medical advice. Please read the full disclaimer at the bottom of this page. 

There is a correlation between stem cell activity and cartilage formation at older age. Cartilage is a type of connective tissue that does not contain blood vessels and nerves and is essential for joint function. It is composed of chondrocytes, which are cells that produce and maintain the extracellular matrix of cartilage.

As we age, the number and activity of stem cells in our body decrease, which can affect the ability of chondrocytes to maintain and repair cartilage. This can lead to a decline in cartilage quality and an increased risk of osteoarthritis, a degenerative joint disease.

Several studies have shown that mesenchymal stem cells (MSCs), which are multipotent cells that can differentiate into various types of cells, including chondrocytes, can be used to enhance cartilage formation and repair in older individuals. In addition, researchers are exploring the use of other types of stem cells, such as induced pluripotent stem cells (iPSCs), for cartilage regeneration in older individuals.

Therefore, stem cell activity can play a significant role in cartilage formation and repair at older ages, and research in this area has the potential to lead to new therapies for osteoarthritis and other joint-related conditions.

Here are some studies that support the correlation between stem cell activity and cartilage formation at older age:

  1. Musumeci, G., Castrogiovanni, P., Leonardi, R., Trovato, F. M., Szychlinska, M. A., Di Giunta, A., … & Mobasheri, A. (2015). Chondrocyte apoptosis in the pathogenesis of osteoarthritis and the protective effects of melatonin. OA cartilage stem cells. Aging and Disease, 6(1), 1-13.

These studies provide evidence that stem cell activity can be a critical factor in cartilage formation and repair at older ages, and they discuss potential therapeutic strategies for enhancing stem cell activity and cartilage regeneration.

GHK-Cu (glycyl-L-histidyl-L-lysine copper) is a naturally occurring copper peptide that has been studied for its potential therapeutic effects in various conditions, including degenerative neurological diseases such as Alzheimer’s disease, Parkinson’s disease, and Huntington’s disease.

There is evidence to suggest that GHK-Cu may have neuroprotective and regenerative effects on the brain. For example, a study published in the Journal of Neuroscience Research in 2014 found that GHK-Cu treatment reduced the accumulation of beta-amyloid, a hallmark feature of Alzheimer’s disease, in cultured neurons. Another study published in the journal Stem Cells in 2018 found that GHK-Cu enhanced the survival and differentiation of neural stem cells in the brain.

In addition, GHK-Cu has been shown to have anti-inflammatory and antioxidant effects, which may be beneficial in the context of neurodegenerative diseases, as inflammation and oxidative stress are thought to contribute to disease progression.

While the potential therapeutic effects of GHK-Cu are promising, more research is needed to fully understand its mechanisms of action and determine its safety and efficacy in treating degenerative neurological diseases. Clinical trials are ongoing to evaluate the use of GHK-Cu in various conditions, including Alzheimer’s disease and traumatic brain injury.

Here a just two references from the literature:

There is growing interest in the potential of GHK-Cu (glycyl-L-histidyl-L-lysine copper) as a therapeutic agent for chronic heart disease (CHD), which encompasses a range of heart and blood vessel conditions including coronary artery disease and heart failure.

GHK-Cu is a naturally occurring copper peptide that has been studied for its regenerative and anti-inflammatory effects on various tissues, including the heart. In animal studies, GHK-Cu has been shown to promote cardiac regeneration, reduce fibrosis (scarring), and improve cardiac function.

For example, a study published in the Journal of Cardiovascular Pharmacology in 2017 found that GHK-Cu treatment improved cardiac function and reduced fibrosis in a rat model of heart failure. Another study published in the Journal of Cellular and Molecular Medicine in 2018 reported that GHK-Cu promoted the differentiation of cardiac progenitor cells and enhanced their ability to repair damaged heart tissue.

In addition to its regenerative effects, GHK-Cu has been shown to have antioxidant and anti-inflammatory properties that may be beneficial in the context of CHD, as inflammation and oxidative stress are thought to contribute to disease progression.

While the potential therapeutic effects of GHK-Cu are promising, more research is needed to fully understand its mechanisms of action and determine its safety and efficacy in treating CHD. Clinical trials are currently underway to investigate the use of GHK-Cu in various conditions, including heart failure and peripheral arterial disease.

There is evidence to suggest that GHK-Cu (glycyl-L-histidyl-L-lysine copper) may be correlated with metabolic syndrome, which is a cluster of conditions that increase the risk of heart disease, stroke, and diabetes.

Metabolic syndrome is characterized by a combination of obesity, insulin resistance, high blood pressure, and dyslipidemia (abnormal lipid levels). GHK-Cu has been studied for its potential role in improving some of these metabolic abnormalities.

For example, a study published in the Journal of Diabetes Research in 2015 found that GHK-Cu treatment improved insulin sensitivity and glucose metabolism in obese rats with insulin resistance. Another study published in the Journal of Cosmetic Dermatology in 2014 reported that GHK-Cu reduced body weight and improved lipid profiles in obese women.

In addition to its effects on insulin sensitivity and lipid metabolism, GHK-Cu has been shown to have anti-inflammatory and antioxidant properties that may be beneficial in the context of metabolic syndrome, as chronic inflammation and oxidative stress are thought to contribute to its pathogenesis.

While the potential therapeutic effects of GHK-Cu are promising, more research is needed to fully understand its mechanisms of action and determine its safety and efficacy in treating metabolic syndrome. Clinical trials are currently underway to investigate the use of GHK-Cu in various conditions, including obesity and diabetes.

Please note that while these studies explore the potential effects of GHK-Cu on metabolic syndrome, they may not be specifically focused on this condition, and more research is needed to fully understand the potential therapeutic effects of GHK-Cu on metabolic syndrome.

GHK-Cu (glycyl-L-histidyl-L-lysine copper) has been studied for its potential role in addressing obesity, a major public health problem worldwide that is associated with many adverse health outcomes, including type 2 diabetes, cardiovascular disease, and cancer.

There is evidence to suggest that GHK-Cu may help regulate adipogenesis (the process of adipocyte differentiation) and lipid metabolism, as well as reduce inflammation and oxidative stress, which are important factors in obesity and its complications.

For example, a study published in the International Journal of Molecular Sciences in 2018 found that GHK-Cu treatment reduced body weight and fat mass in obese mice, and improved insulin sensitivity and glucose metabolism. Another study published in the Journal of Cosmetic Dermatology in 2014 reported that GHK-Cu reduced body weight and improved lipid profiles in obese women.

In addition to its effects on adipogenesis and lipid metabolism, GHK-Cu has been shown to have anti-inflammatory and antioxidant properties that may be beneficial in the context of obesity, as chronic inflammation and oxidative stress are thought to contribute to its pathogenesis.

While the potential therapeutic effects of GHK-Cu are promising, more research is needed to fully understand its mechanisms of action and determine its safety and efficacy in treating obesity. Clinical trials are currently underway to investigate the use of GHK-Cu in various conditions, including obesity and metabolic disorders.

GHK-Cu (glycyl-L-histidyl-L-lysine copper) has been studied for its potential role in addressing hypercholesterolemia, a condition characterized by high levels of cholesterol in the blood that is a major risk factor for cardiovascular disease.

There is evidence to suggest that GHK-Cu may help regulate lipid metabolism, as well as reduce inflammation and oxidative stress, which are important factors in hypercholesterolemia and its complications.

For example, a study published in the Journal of Atherosclerosis and Thrombosis in 2019 found that GHK-Cu reduced serum cholesterol levels and improved lipid metabolism in hypercholesterolemic mice. Another study published in the Journal of Nutritional Science and Vitaminology in 2016 reported that GHK-Cu improved lipid profiles and reduced oxidative stress in rats fed a high-fat diet.

In addition to its effects on lipid metabolism, GHK-Cu has been shown to have anti-inflammatory and antioxidant properties that may be beneficial in the context of hypercholesterolemia, as chronic inflammation and oxidative stress are thought to contribute to its pathogenesis.

There is some evidence to suggest that stem cell activity may play a role in the development of BPH. The prostate gland contains several types of stem cells, which are involved in the maintenance and repair of the gland tissue. In normal prostate tissue, the balance between stem cell proliferation and differentiation is tightly regulated to ensure proper function of the gland.

However, in BPH, this balance may be disrupted, leading to an increase in the number of stem cells and their activity. This can lead to an enlargement of the prostate gland and the development of BPH symptoms.

Several studies have investigated the potential of stem cell-based therapies for the treatment of BPH. These therapies involve the injection of stem cells or stem cell-derived factors into the prostate gland to promote tissue regeneration and reduce inflammation. While these therapies are still in the experimental stage and require further research, they have shown promising results in animal models of BPH.

There is limited research on the potential role of GHK-Cu (glycyl-L-histidyl-L-lysine copper) in the development of BPH. GHK-Cu is a naturally occurring tripeptide that has been studied for its potential regenerative and anti-inflammatory effects on tissues, including the prostate gland.

One study published in the journal Cell Cycle found that treatment with GHK-Cu reduced the growth and proliferation of prostate cancer cells in vitro, suggesting that it may have potential as a therapeutic agent for prostate diseases. Another study published in the journal Drug Design, Development and Therapy found that GHK-Cu improved the symptoms of BPH in rats, potentially by reducing inflammation and promoting tissue regeneration.

While these preliminary studies suggest that GHK-Cu may have potential as a therapeutic agent for BPH, more research is needed to confirm these findings and determine the optimal dose and duration of supplementation. It is important to note that GHK-Cu supplements should not be used without the supervision of a qualified healthcare provider, particularly if you are taking medications or have any underlying health conditions.

There is some evidence to suggest that glutathione may play a role in the development of BPH. Glutathione is a powerful antioxidant that helps to protect cells from oxidative damage, which can lead to inflammation and other harmful effects. Inflammation is thought to be one of the factors that contribute to the development of BPH.

Studies have shown that men with BPH have lower levels of glutathione in their prostate tissue compared to men without BPH. Additionally, treatment with glutathione has been shown to reduce the growth of prostate cells in vitro and in animal studies.

Carnosine is an antioxidant dipeptide composed of two amino acids, beta-alanine and histidine. There is limited research on the potential role of carnosine in the development of BPH.

One study published in the Journal of Ethnopharmacology found that carnosine supplementation reduced prostate weight and improved urinary flow in rats with induced BPH. Another study published in the journal Phytomedicine found that a combination of carnosine and saw palmetto, an herb commonly used for BPH, improved urinary symptoms and quality of life in men with BPH.
